It's more than climate change and active transport-physical activity's role in sustainable behavior.

Considering the interdependence of human's and nature's health within the planetary health concept, we evaluated how physical activity (PA) can be conceptualized as sustainable behavior (SuB) and how PA relates to other types of SuBs within the United Nations' sustainable development goal (SDG) framework. Regarding social SDGs, PA contributes to improving malnutrition (SDG 2), health behaviors (SDG 3), education (SDG 4), reducing inequalities (SDG 10), sustainable cities (SDG 12), and peace (SDG 16). For ecological SDGs, PA contributes to sustainable consumption (SDG 11) and combating climate change (SDG 13). Therefore, PA is more than a health behavior, it contributes to planetary health and sustainable development. However, caution is warranted as PA also has the potential to contribute and reinforce unsustainability. Thus, PA as a SuB requires an own research agenda, investigating (a) PA as social and ecological SuB, (b) sustainable PA promotion, (c) sustainable PA measurement, (d) common underlying constructs of PA and SuB, and (e) technology's role to assess and promote PA and SuB.
